AUTOMOBILE-Rm.

To all whom it may concern:

7 Be it known that I, J UDSON H. Mxsnmmq,

a. citizen of the United States, residing at Glendive, in the county of' Dawson and State of Montana, have invented certain new and useful Improvements. in Automobile-Rims, of which the following is a specification.

This invention has relation to demountable rims, for pneumatic tires, and has for an object to provide. a demountable rim of a new and novel-character adapted to permit the instant removal of the mm from the tire in an easy and eflicacious manner I Another object of the invention is to provide a demountable rim of the character ahoie described which is formed in a plurality of hingedly connected sections, whereby. the rim may be collapsed while in position within the tire casing thereby insuring the quick detachment of the rim from the tire.

In addition to the foregoing my invention homprehends improvements in the details of construction and arrangement of the parts to b,ehereinafter more fully described and particularly set forth in the appended claims.

In the accompanyin drawings in which similar and correspon mg parts are deslgnated by the same characters of reference throughout the several views in which they appear Figure 1, is a view in side elevation ofa tire applied to my improved demountable rim, illustrating the collapsed position of the parts of the rim in dotted lines, and

Fig. 2, is a section taken on the line 2-2 of the preceding figure.

With reference to the drawings, 10, 11, and

12, indicate the three sections of my de- -mountable rim, shown in the present instance as adapted to receive a pneumat c tire casing of the-clencher type, although it may be apparent thatthe rim may be utilized in con- .nection with tire casings of other types. The

section 10 is equal in length to approximately two-thirds the circumference of the rim, the

sections 11 and 12 occupying jointly the remaining one-third. The terminals of section 10 are connected to the remote ends of sections 11' and -12 through the medium of hinges 13 which are applied to the inner sur ace of the rim. The adjacent ends of the sections 11 and 12 are beveled as at 14 whereby the line of the'joint between the sections when they are in circumferential alinement is at an angle to the lineal side it being noted Specification of Letters Patent. Application filed June 19, 1913. Serial No. 240,104.

Patented May 13, 1919.

however, mat one section is slightly shorter than the other, the shorter section in the present instance being the one indicated at 11.

The adj acent ends of said sections 11 and 12 are connected together by means of a hinge 15 which is applied to the exterior surface of the rim within the clencher edges thereof and said hinge comprises a short leaf 16 secured to the section 12,'and a long leaf 17 which extends across the joint between the sections and is secured to the section 11. The pintle of the hinge 15 is located at a point exactly midway of the hinges 13.

In use, when it is desired to disengage the mit the tire to strike upon an object at a point adjacent the pintleof the hinge 15 and the blow will result in the disengagement of the sections 1.1 and 12 from the clencher rim demountable rim to the tire casing being as readily and quickly accomplished.

\Vhile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations thereover may be made, and I therefore derim from the tire it is but necessary to persire to reserve the right and privilege of changing the form of'the details of construction, or otherwise altering the arrangement of the correlative arts without departing from the spirit of t 1e invention or the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 2'-- i 1. A demountable rim including a section equal .in length to approximately two-thirds the circumference of the rim, a pair of sections equal in length jointly'to the remaining third of the circumference, one of'said men tioned sections bein slightly shorter than the other, hinges app ied to the internal s'ur-. face of the sections to connect the terminals of the first mentioned section with the remote ends of the second mentioned section. and a hinge member applied to the external surface of the second mentioned sections for hingedly connecting their adjacent ends.

2. demountable rim including one section equal in length to approximately'twothirds the circumference of the rim, a pair of sections j ointly equal in length to the remaining one-third of the circumference, one of said sections being slightly shorter than the other and the meetin ends of said sections beveled, hinged mem ers secured to the internal surface of the rim to connect the terminals of the first mentioned section with the remote ends of the second mentioned sections, and a hinge member secured externally to the rim to connect the adjacent ends of the 15 second mentioned sections, said hinge comprising a short plate secured to the longer of the second mentioned sections, and a long plate to extend across the joint between the second mentioned sections, and secured to the 20 shorter section.

In testimony whereof I afiix my signature in presence of two witnesses.
